Hi.

Did look on probably all of topics, but couldn't find solution.

Recently bought Superb with CRLB engine, 128k miles.

Just spotted on my DPF regens so often, roughly every 50-60 miles on steady run outside a town.

Been done so far:

- Replaced oil and filter

- checked pipe connected to DPF sensors

- chemically cleaned DPF 

 

Car sometimes loosing a power for maybe 1 minute. Injectors has been looked on computer and all looks ok, car starting without problems, fuel consumption is on normal level. Car doesn't take a oil (I've done so far 3k miles and didn't get any low oil warning light).

Just observed on Vag DPF, Soot mass measured going up very quick. Trough regens all going fine, i mean decent temperature and whole process going correct.

Have you the correct engine code selected? On my version there are 2 the same. 

Here's mine for comparison:

Yes, CRLB code, correct engine for me.

Shouldn't they reset the DPF when it was cleaned?

Have a no idea, guys never mentioned anything about reset settings. First run after cleaning I get 120 miles to regen, but after then everything back to normal, I mean 60 miles routine 😕

I’d go back to them and say oi

In theory, if you are currently driving 60 miles with DPF full with ash in 70%, you should do 180-200 miles if it's new or cleaned. Of course, cleaned DPFs are never perfectly clean and ash-free, but at least reseting its ash levels should be a starting point.

I don't know where are you located, but I've watched some YT videos of this guy fixing DPFs and he really knows what he's doing https://www.facebook.com/rileysautosmechanic/

I wouldn't  be so sure, have a read of this https://www.pistonheads.com/gassing/topic.asp?h=0&f=&t=2078589

Just read it, but my car is 128k miles now and I scan it everyday but unfortunately there aren't any error messages. No dpf light either. Regens just working as should, get proper temperature, soot going down, takes roughly 15-20 mins to clean out, but just after regen measured soot mass going up very quickly 😕
